Taking matter into own hands, Lord Allard Royce of Runestone gathered forces to sweep away Jonos's supporters, penning him at the Eyrie. However, this led Jonos to send his brother flying out of the Moon Door, earning him the nickname Jonos the Kinslayer.[1][3]

Jonos and his garrison remained defiant until Prince Maegor Targaryen flew to the Eyrie atop the dragonBalerion. Rather than face the fire, Jonos was seized by his garrison and delivered to Lord Royce through the Moon Door. Surrender saved Jonos's followers from burning, but not from death. All of them were hanged per the orders of Maegor, who denied the highborn rebels the honor of beheading.[3][1]House Arryn continued through a kinsman after Ronnel and Jonos' deaths, a cousin, Hubert Arryn.[3][4]
